Problems solved by technology

[0003] The two-wheel steering is easy to control, but the turning radius of the vehicle is large, the stability is poor when turning at high speed, the space required for parking is large, and it is inconvenient to enter and exit
Four-wheel steering can overcome the above defects of two-wheel steering, but the structure of the control system is complicated and the cost is high, so it is mainly used in high-end cars

Abstract

An auxiliary steering unit for vehicle features that the existing steering wheel and steering mechanism have an additional steering function performed by wheel drive and ground's reactive force. Its method is to install a motor to each wheel in such manner that the axis of wheel and drive motor can revolve around a vertical axle which can be locked or released by a lock unit. As a result, a car can run transversely by 90 deg or turn back by 180 deg. in situ.

Description

technical field [0001] The invention relates to the field of electrically driven vehicles, in particular to a steering device for an electric vehicle. Background technique [0002] As a clean and efficient means of transportation in the post-petroleum era, electric vehicles have attracted more and more attention. However, with the continuous development of society, the number of vehicles is increasing, and the roads seem a little narrow, and the space required for parking vehicles is becoming more and more tense. So in the process of parking or U-turn will cause vehicle jam phenomenon, its main cause is due to the incomplete function of existing vehicle steering gear. The steering mechanism of existing vehicles mostly adopts two-wheel steering under the control of steering wheel and steering gear, and a few high-grade cars adopt four-wheel steering. [0003] Two-wheel steering is easy to control, but the turning radius of the vehicle is large, the stability is poor when tu...
